2. Description of the Prior Art

Ice blocks are widely used in most homes. They can be used for concocting drinks, freezing food or temporarily keeping food fresh, or even used for reducing a swelling or fever. A common method for making ice blocks in a home is to pour water into an ice-making box and then put the ice-making box into the freezing compartment of a refrigerator for making ice blocks.

However, apart from making ice blocks, a family refrigerator is employed for preserving food; therefore, in a process of making ice blocks, the water in the ice-making box may absorb various flavors of food in the refrigerator. In addition, it needs to take about an hour to make ice blocks in a conventional family refrigerator and the amount of the ice blocks made in the refrigerator is limited, unable to make ice blocks to meet urgent needs.

Additionally, if there is not any ice-making box for making ice blocks in a conventional family refrigerator, other kinds of containers have to be used instead, but the ice blocks made by these containers are different in size and difficult to be separated from the containers, resulting in much trouble in use.

SUMMARY OF THE INVENTION

The objective of the invention is to offer an ice-making machine able to quickly make ice blocks regular in size.

The ice-making machine of this invention includes a machine body having its surface provided with a control faceplate and its interior formed with a water tank and an accommodating hollow.

The machine boy 1 is provided with a control faceplate 10 on a front side and formed with a water tank 11 and an accommodating hollow 12 respectively in the front interior and in the rear upper interior. The water tank 11 has its bottom bored with a water intake 110 having its rear end connected with a water pipe 111 and a pump 112. Further, the water tank 11 is provided with a support edge 113 and the accommodating hollow 12 has one upper end provided with a feed water pipe 120 connected with the water pipe 111. A draining channel 13 is formed between the accommodating hollow 12 and the water tank 11 and has its upper side assembled with a cover 14 having a sensor 140 installed therein, with a draining port 121 formed between the cover 14 and the accommodating hollow 12. The accommodating hollow 12 is bored with an insert hole 122 and a slit 123 at one side and fixed with a water-trough positioning stud 124 at the other side opposite to the insert hole 122. A holding plate 125 and a stop block 126 are provided at the same side of the water-trough positioning stud 124. Further, the machine body 1 is installed with a trigger switch 15 on the outer wall of the accommodating hollow 12 at a location corresponding to the insert hole 122. The trigger switch 15 is provided with a trigger member 150 to be fitted with one pivot 21 of the water trough 2 and two trigger blocks 151 respectively positioned at a corresponding location of the opposite sides of the trigger member 150 and respectively having a trigger strip 152 fixed thereon.

The water trough 2 is pivotally assembled in the accommodating hollow 12 of the machine body 1, having a push plate 20 pivotally assembled at the front side. The water trough 2 further has its opposite sides respectively fixed with the pivot 21. The pivot 21 at one side of the water trough 2 is inserted through the insert hole 122 of the accommodating hollow 12 and fitted with the trigger switch 15, while the pivot 21 at the other side is pivotally assembled with the water-trough positioning stud 124.

The freezing system 3 installed in the interior of the machine body is composed of a compressor 30, a condenser 31, an electric magnetic valve 32, a dryer 33, a vaporizer 34 and a liquid reservoir 35. The compressor 30 positioned at the rear side of the machine body 1 is provided with a condenser connecting pipe 300 and a liquid-reservoir connecting pipe 301 respectively connecting the condenser 31 and the liquid reservoir 35. The condenser 31 is provided with a compressor adapter 310 and an electric magnetic valve adapter 311 to be respectively connected with the condenser connecting pipe 300 of the compressor 30 and the condenser connecting pipe 320 of the electric magnetic valve 32. Further, the condenser 31 has a fan 312 assembled at one side. The electric magnetic valve 32 is provided with a condenser-connecting pipe 320 and a vaporizer-connecting pipe 321 to be respectively connected with the condenser 31 and the vaporizer 34. The dryer 33 is connected with the end of the condenser 31 and has its upper end connected with a capillary tube 330 having its end linked with the vaporizer-connecting pipe and connected with the vaporizer 34. The vaporizer 34 is provided with a liquid-reservoir connecting pipe 340 and an electric magnetic connecting pipe 341 for respectively connecting the liquid reservoir 35 and the electric magnetic valve 32. Further, the vaporizer 34 combined with the holding plate 125 and positioned above the water trough 2 has its underside provided with a plurality of ice-making rods 342. The liquid reservoir 35 has one end connected with the vaporizer 34 and the other end connected with the liquid reservoir connecting pipe 301 of the compressor 30.

The lifting cover 4 is covered on the machine body 1.

The ice-collecting box 5 is positioned on the support edge 113 of the water tank 10 of the machine body 1 and provided with a separate ladle 50 for ladling out ice blocks 6 for use.

In operating, as shown in FIGS. 4˜13, firstly, press a starting button through the control faceplate 10 of the machine body 1 to let water flow into the water pipe 111 through the water intake 110 of the water tank 11 and then pumped into the water trough 2 through the feed water pipe 120 by a pump 112. After the water trough 2 is filled up with water, the overflowing water of the water trough 2 will flow into the water tank 11 through the draining port 121 at the side of the accommodating hollow 12 and along the draining channel 13 to actuate the freezing system 3 to begin carrying out water freezing and ice making. In an ice making process, the compressor 30 of the freezing system 3 is started to have the refrigerant in the pipes pumped into the condenser 31. (The circulation direction of the refrigerant is shown by the black arrows in FIG. 7 and at this time the electric magnetic valve 32 is in a closed condition). Then, the refrigerant is conveyed into the vaporizer 34 through the dryer 33 and the capillary tube 330 and at this time, the refrigerant, due to the principle of volume expansion, evaporation and heat-absorption, will make the vaporizer 34 function to make ice. Since the ice-making rods 342 provided under the vaporizer 34 are extended into the water trough 2; therefore, water around the circumference of each ice-making rod 342 will quickly be frozen into ice block 6. After ice blocks 6 are frozen in shape, unfreezing work is to be carried out for separating the ice blocks 6 from the ice-making rods 342.

In unfreezing, as shown in FIGS. 6-13, firstly, start the trigger member 150 of the trigger switch 15 to rotate and actuate the water trough 2 to turn over upward to pour out of the water therein, and simultaneously the water will flow into the water tank 11 along the draining channel 13. When the trigger member 150 is rotated to touch and press the trigger strip 152 of the other trigger block 151, unfreezing and ice-separating work will be started. At this time, the electric magnetic valve 32 is turned off; therefore, the refrigerant sucked in the compressor 30 from the liquid reservoir 35 will circulate along two routes, that is, it will circulate along the original ice-making pipes and circulate to the vaporizer 34 through the electric magnetic valve 32, as shown by the black and the hollow arrows in FIG. 7. Since the refrigerant pumped out by the compressor 30 is of high temperature and high pressure and such refrigerant passing through the electric magnetic valve 35 is in large quantity; therefore, the heat energy of the refrigerant passing through the electric magnetic valve 35 is higher than that passing through the capillary tube 330, hence having function of unfreezing.

Thus, the ice blocks 6 can be separated from the ice-making rods 342 to drop into the accommodating hollow 12, and afterward the trigger member 150 will actuate the water trough 2 to turn back to its original position. In the meantime, the push plate 20 pivotally assembled at the front side of the water trough 2 will move together with the water trough 2 and shovel the ice blocks 6, which will then slide into the ice-collecting box 5 along the push plate 20, as shown in FIG. 12. When the ice-collecting box 5 is filled up with ice blocks 6, the superfluous ice blocks 6 of the ice-collecting box 5 will lean on the sensor 140, letting the sensor 140 sense the icy temperature and stop the ice-making machine from making ice blocks any longer, as shown in FIG. 13.

The ice-making machine of this invention can make ice in a short time (about ten minutes) and can carry out unfreezing conveniently for using the ice blocks immediately, and additionally ice blocks can be made according to the amount required.

In addition, the process of freezing and unfreezing can be controlled by turning on or off the electric magnetic valve 32, and the ice making and unfreezing work can be controlled by presetting time or temperature, and a temperature sensor could be provided on the vaporizer or on the water trough.

While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
